replaced, it is necessary to first remove the horizontal bar, or so-called' binder, by which the wedge-bolt is supported.

This operation involves considerable time and labor and it is the object of my invention to provide an improvement whereby the removal of the wedge-bolt can be very easily and quickly effected.

The details of construction, arrangement, and combination of parts are as hereinafter described, and illustrated in the accompanying drawing, in Which Figure l is a vertical section of a portion of a locomotive frame, together with journal bearings and my improved attachment applied thereto. Fig. 2 is an enlarged ver tical section illustrating particularly the means for supporting and adjusting the wedge. Fig. 3 is an enlarged longitudinal section of the screw collarin which the bolt for adjusting the wedge is arranged. Fig. 4 is a plan View, and Fig. 5 is a longitudinal section of theso called binder. Fig. 6 1s a perspective view of the screw collar of, the adjusting wedge-bolt. Fig. 7 is a sectional view further illustrating the construction and arrangement of wedges for securing the brace or hinder to the locomotive frames.

Referring in the first instance to Fig. 1, the numeral 1 indicates an axle-journal, 2 the block or bearing for the same, and 3 the locomotive frame in whose vertical slot the block 1 is arranged. 4 indicates the wedge which is inserted in a cavity or recess on one side of the journal-block 2 and whose outer or inclined side is in sliding contact with the correspondingly inclined side of the adjacent frame. The wedge 4 is supported upon, and adjusted by, a screw-bolt 5 having a conical head which is in contact with the Wedge and adapted for lateral in- Sertion in opposite grooves 6, which are preferably dove-tailed so that the shoulders of the bolt head engage the wedge.

The wedge-bolt 5 passes through a socalled collar 7, shown detached in Figs. 3 and 6. The body of this collar is cylindrical and screw-threaded internally and externally, and the head, which is narrow in one direction, extends horizontally, thus formmg" ears which, when the collar is arranged in a slot 8 provided in the binder or horizontal bar 9, extend across and rest upon the binder, as in Figs. 1 and 2. The wedge- Ebolt 5 is screw-threaded and thus adapted ,to engage the thread-formed in the upper gportion of the collar 7 and a nut 10 is applied to the lower end of the collar, as shown. A jam-nut 11 is also applied tothe so that it is immovable.

Theears 7 ofthe collar rest in notches 9 formed in the top of the binder 9, so that the collar cannot rotate when the parts are in-the position shown in Fig. 1, and the nut 10 is being screwed home to hold the collar in place. The lower end of the wedge-boltof adjusting the wedge 4 higher or lower. The slot 8 in the binder 9 is long enough to permitthe lateral adjustment of the collar {.7 and wedge-bolt 5' held therein, so that gthese parts may be placed in the position Zshown by full lines in Fig. 1.-

K In order to place the parts-in position, the ibo'lt 5 is screwed into the collar 7 and the latter then inserted up through the slot 8 and the ears or extended head of the collar lower end of the bolt and locks the nut' 10 5 is squared to provide for the application of a wrench for turning it, for the purpose areturned crosswise of the binder, as shown by dotted lines in Fig. 4. The wedge-bolt 5 and collar 7 are then adjusted laterally into the position shown by full lines in Fig. l, the conical head of the bolt 5 entering the groove 6 in the wedge and the ears 7* of the collar dropping into the notches 9 of the binder. Then the nut 10 is turned to draw the collar 7 tightly. into place, and the wedge-bolt 5 is rotated to adjust the wedge tightly as required. The am-nut 11 is next rotated to lock the nut 10 and the operation is repeated.

In order to disengage the wedge-bolt 5 from wedge 4, the adjusting bolt 5 is loosened and also the collar 7, so that they may be slid together laterally to the right, and into the position indicated by dotted lines in Fig. 1. The binder or brace 9 is provided frame lugs 12, so as to clamp the binder tightly thereto.

What I claim is l. The combination with a locomotive frame, an axle-journal bearing, a wedge, and. a horizontal bar beneath the bearing and wedge, of a bolt extending through an opening in said bar, a collar surrounding and adapted to retain said bolt within the opening, means on the upper end of said collar engaging said bar.

2. The. combination with a locomotive frame, an aXlejournal bearing, a wedge,

and ahorizontal bar beneath the bearing and wedge, of a bolt extending through an opening in said bar, a collar surrounding said bolt provided with an interior threaded portion, a holding means on end of said collar, and means on the body of the collar engaging said bolt to retain the device when said holding means is in operation.

3. The combination with a locomotive frame, an axle-journal bearing, a wedge, and a binder beneath the bearing and wedge, of a bolt extending through an opening in said binder, a collar surrounding said bolt the bottom surface of the binder, and oppositely disposed laterally extending lugs and its upper end adapted to engage a recess in porting it in the slot of the bar, as described.

5. The combination, with a slotted locomotive frame, a ournal-block arranged in the slot, and a wedge arranged between them, as described, of a horizontal bar arranged below the ournal-block and secured to the frame and provided with a lengthwise slot at a point directly below the wedge, and a device for adjusting the bolt vertically, the same consisting of a screw-bolt and a screw-threaded collar through which it ;passes, said bolt and collar being adapted for support in the slot of the bar and for adjustment laterally to one side of the wedge, as set forth.

6. The combination, with a frame, an axlebearing block and wedge coacting therewith, of a horizontal bar secured below the bear- 5 ing and provided with a longitudinal slot jand notches formed in the upper side, a j screw bolt and a screw-collar through which jit passes, said collar being arranged in the 3 slot of the bar and provided with lateral extensions adapted to fit in the aforesaid notches of the bar, as described.

provided with an interior threaded portion, a nut on its lower end engaging a recess in E WILLIAM CURRY STEPHENSON.
